Adding Desser 8,50 smoothies to 182 for landing unimproved strips; some rough native prairie/pasture grass as well as backcountry. Will run mid teen PSI to minimize shock to airframe. In order to stop low PSI tube type tires from slipping on the wheel when heavy braking is applied; I've heard of gluing tire bead to wheel or drilling small holes (#10 screws) and using screws to lock tire bead to wheel. Looking for real world experience for either method or any other ideas. Our 182 flying will probably be 60% hardsurface and 40% other so the softer ABWs won't last. Had great luck with these Dessers on Champ but 182 being heavier will probably require a little extra help.

If you don't want to post your methods publicly, please PM me.
Thanks

Been running 850's on my 172 and now 182 for 10 years. No issues what so ever with slip. I run 15-20 psi. No need to over think this.

Most important:

1. Place slippage marks on tire/wheel junction.

2. Make checking tire pressures a REGULAR process. Natural rubber tubes leak some, but they are all I will run. Desser synthetic or “leak proof” tubes are awful. Too many faults.

Otherwise, just run them.

What he said.
I like to air the shit out of MLG tires when I mount them in order to seat the bead good and hard.
Up to maybe 50 psi, then back it down to 15-20.
I run 850 airtracs on my 180, fill to 20.
When it starts getting hard to pull the plane into the hangar,
they're down to about 15 -16, and I pump them back up to 20.

Good to know; OWTs die hard sometimes.
Thanks

Well, they're really not old wives tails, necessarily.

Back in the day, tire options were limited, and some very large tires (think dragster slicks, etc) were sometimes used on airplanes. Some of those tires, run at very low pressures, really needed to be "staked", or screwed to the rims. Understand that these rigs were being used really rough and tough, and those very large diameter tires impart a LOT of torque when accelerated quickly upon landing.

BUT, with 8.50 x 6 tires, properly seated like 180 noted, and pressure monitored regularly, you shouldn't have any problems. With most of these tires (and I have not run the Desser 8.50s), it's almost impossible due to side wall stiffness, to determine at a glance whether they need air. Carry a low pressure gauge, and check them regularly.

Thanks all; Mike, the Dessers are 4 ply and sidewall is pretty flexible. That is why I'm going with them. I don't have much off paved RW time on a heavier (182) plane so I'm kind of experimenting here. Fair amount (7 yrs mostly easy stuff) SC with 26 GY= pretty stiff for lighter plane (12 PSI) and 31s on Husky- mostly used for landing shock absorption (makes bad landings look better ) with occasional soft sand and rocks. BTW; wife/I try to land 60-70% off pavement and these tires are now over 3 yrs and 400 hrs= wearing better than expected.
